Bionic Guzz Fun kit - Vertical format

In stock format this is a five-knobber with Level, Fuzz, Filter, Bias and Density controls, as well as a toggle switch to kick in oscillation mode which is more fun than a bucket of badgers. We've added the option of replacing that switch with a pot for adjustable levels of insanity. Though labelled as 'Oscillation', the pot works more like the stability control on a Fuzz Factory, with fully clockwise being entirely un-oscillatey, and more madness being brought forth when the pot is wound back.

You can also opt to have no oscillation control at all, keeping the knobs to a minimal five.

The circuit is a bit picky about the input signal, so this works best without a buffer in front of it.

Optional extra transistors are available so you can experiment with making it a bit less gated - these are now MPSA06 and BC517 - the results can be a lot more pleasing than the standard cans.

Pots are spaced 17.5mm apart, so take that into consideration when choosing your knobs.
